I just tried that file and it loaded instantly. I also don't see any problems with the Quality rendering option. If I switch to "Speed", it renders without chords as you showed in your second screenshot. If you switch to quality and you still don't see chords, that means that the quality PDF rendering library is corrupted, and it's falling back to the "speed" option. It doesn't sound like this is the case though. Can you try updating to v1.5.3 and see if this fixes anything? Also, just to verify, were you running v1.5.0 before you updated to v1.5.2?
Thanks,
Mike
